IUCN status: Vulnerable
EPBC Threat Rating: Very high
IUCN claim: “The species is threatened by introduced predators, the red fox and feral cat especially”
Foxes hunted 3 of 30 reintroduced, predator-inexperienced wallabies (Hayward et al. 2012).
Wallabies were last confirmed in NSW 3 years before foxes arrived (Table S2).
There are no studies evidencing a link between foxes and nail-tail
wallaby populations. In contradiction with the claim, the extirpation
record pre-dates the fox arrival record.
Evidence linking Onychogalea fraenata to foxes. A. Systematic review of evidence for an association between Onychogalea fraenata and foxes. Positive studies are in support of the hypothesis that foxes contribute to the decline of Onychogalea fraenata, negative studies are not in support. Predation studies include studies documenting hunting or scavenging; baiting studies are associations between poison baiting and threatened mammal abundance where information on predator abundance is not provided; population studies are associations between threatened mammal and predator abundance. B. Last records of extirpated populations relative to earliest local records of foxes. Error bars show record uncertainty range. Predator arrival records were digitized from Fairfax 2019.
